Define frameshift mutation. Then give an example of this type of mutation, both at the DNA and protein level, and explain what effect this mutation would have on the protein’s function.

The binding of a ligand to a receptor protein is which stage of cell signaling?

The following image show a gel at the end of gel electrophoresis. Well 1 was filled with a control, the exact DNA sequence we are looking for. Wells 3 and 5 were filled with DNA extracted from two different samples. Which of these samples does not contain the DNA sequence we are looking for? Choose all that apply.         [Image ID: Gel with 6 wells, 3 used. Well 1 contains control. Well 3 contains Sample 1. Well 5 contains Sample 2. Bars are seen on the gel in 3 areas: top, middle, bottom. Well 1 shows only top bar, Well 3 shows top and middle, Well 5 shows top and bottom.]
